To all whom it 'H'Lay concern:

: Beit known that 1, James 1%. Mnnsnnnn,

acitizen of the United States, residing at Eilwampscott, in the county. of ,Essex and litate of Massachusetts; have invented new and useful Improvements in Heeled Shoes,"

of which the following is a specification.

This invention relates to a shoe having a heel the breast of which forms one side of a space between the tread faces of the heel and. the outer sole, the word shoe. being intended toapply to any. article offootwearthus characterized- Tl'ie ob ect of the ll'lVGIl't'lOn s to provide ashoe, theheel of which is forwardly extended at its breast end to adequately supk port that 'portionwof the bottom of the foot located under the forward portion of the bone known. as the oscalsis or calcaneum,

without imparting to the heel an undesir ably clumsy andbulky appearance, so that the aspect of. the heel does not differ materially from that of a standard heel, the

breast of. which is notjforwardly extended.

yfllhe invention is embodied in the improvements hereinafter described and cla med/g Of the accompanying drawings forming.

apart of this specification,- Figure 1 1s a side v1ew of a shoe embodyinn; the invention, showing by dotted lines a side view of the skeleton of lnunan foot w1th1n the shoe.

hating portions of'the shoe heel) is the ee.

tion directly under the oscalsis or calcaneum 0, and. under a portion of the astragralus a. The downwardly facing surfaceof the oscalsis has at its forward portion a contour conforming approximately to the dotted lines 14;, 1.4-. The calcaneun is at the rear. end of the arch of the foot, and its forward portion projects forward from the br ast of the shoe heel as ordinarily formed, and considerably. overhangs the breast of an ordinary heel, the proportions of which are dictated by custonn and are such that the breast is so far behind the forward portion of the bones above named, thatthe for ard not adequately support these bones. i i r i The ends: of the breast are usually on a line at right angles with the median. line Z), Z), the breast beingeither straight, or having; a reentrant curvature between said ends. I

In a heel conforming to the dictates of custom or fashion, the ends of the breast aortion of the bones above named at the medianline of the shoe. The curved margin 12 of the heel is of minimum length; from end to end of the breast. Bythis, I mean that the forward projection of the ends of the curved margin from the median line of the back oit' the heel is practically the same in a standard heeh so that said margin when viewed from either side, is not objectionably elongated. The ends of the breast are substantially in aiinenient with each other, on a line at right angles with the median line so that they a abreast of each other, neither projecting forward of the other.

The breast is salient and has aforwardly projecting crown or apex 13, located midway between its ends and extending substantially perpendicular to the tread face of. the top lift; The crown is preferably formed by theintersection of two oblique faces 14;, said intersection forming an obtuse angle at 13, although the breast may have a curved crown 13 as shown by Figure 6. The crown may be formed by the intersection of two concave faces 14:, as shown at 13", Figure 7.

It will now be seen that the breast formed as described, provides an extension of the heel, adapted to conform approximately to that portion of the bottom of the foot which is under'the forward portion of the oscalsis,

and under a considerable portion of the astragalus, and that the 'heel having said extension is formed to more adequately support the said bones at the median line of the tread, than an ordinary standard heel, as may be seen by the dotted lines 20 and 21, (Figure 1). The line 20 is an extension of the crown 13, and the line 21 is an extension of the central portion of the breast of an ordinary heel. If the breast is concave, as is usually the case, the line 21 will be more widely separated from the line 20, and nearer the rear end of the heel.

The .form of the breast is such that the said extension has a limited visibility. I mean by this, first, that when the shoe is viewed from either side, in the direction of the (arrow ac (Figure 4), the breast, while visible, is in the shadow of the shank portion of the outer sole, as indicated by Figure 1, so that it is not objeotionably conspicuous; and secondly, when the shoe is viewed obliquely in the direction of either of the arrows z andz, the apparent length of the heel is not greater than the distance'between the rear end of the heel and the breast ends 15, the breast being invisible when viewed in the direction of the arrow 7 The said extension enables the heel to be united to the outer solo by a fastener 18, inserted in the inner and outer soles, the usual shank stiffener between said soles, and the extension forward of the ends of the breast, as indicated by dotted lines in Figures 1 and 2, said fastener supplementing the usual heel-attaching nails. and increasing the strength of the connection between the heel and the bottom of the shoe.

The heel may be provided with a cushioning top lift of rubber or other material, having a breast of the form described.

I claim:

A shoe having a heel, the curved margin of which is of substantially the length of a standard heel, the breast ends being substantially in alignment with each other on a line at right angles with the median line of the shoe and considerably in rear of the portion of the innersole which comes beneath the forward end of the oscalsis of the wearers foot, and having a forwardly projecting crown extending from the ends of the breast to said median line and under that part of the wearers foot which is beneath the forward portion of the oscalsis, said extension being adaptedto support said portion of the foot at the median line of the tread and having a limited lateral visibility.

In testimony whereof I have affixed my signature.

JAMES F. MARSHALL.
